You can just use 'git log --abbrev-commit' to get commit IDs abbreviated
(enough for nonambiguity and no further).

If you want to enable this forever, git 1.7.6+ lets you say

git config log.abbrevCommit true

(add --global or --system to make it apply to all repositories for this
user, or all repositories on the system, respectively).

In addition in addition, git-new-workdir (a script in git's contrib/
directory, likely to be installed by default eventually in some form or
other) will let you check out more than one branch at once on the same
repository.
